ara

A basic reimplementation of grep using C.

Why

I have little experience with the C language and want to learn more of it. No AI agents will be used in this project.

I won't be aiming for full feature parity with grep. Currently supported optional arguments:

• -i Case insensitive search
• -n Print line number with output lines
• -v Invert matches (select non-matching lines)
• -m stop after N matching lines

How to build and use

You should first compile the main.c file into a binary:

gcc -o ara main.c -lm

This will compile ara into a binary named ara.

Now, you can use ara just like you would use grep:

./ara "error" server.log

An example:

./ara -in "millet" istiklal-marsi.txt

Output:

3: O benim milletimin yıldızıdır, parlayacak;
4: O benimdir, o benim milletimindir ancak.
8: Hakkıdır, Hakk’a tapan, milletimin istiklâl.
41: Hakkıdır, Hakk’a tapan milletimin istiklâl!
